Recent radio observations with the Low Frequency Array (LOFAR) have shown striking,
very thin filamentary structures in linear polarization that extend over more than 4 degrees across
the sky. In parallel, the Planck Satellite team has been able to construct a map of the orientation of
the magnetic field of our Galaxy across the sky using their dust all sky polarisation maps. In general,
the two datasets are thought to probe very different physical quantities. In this talk I report on the
surprising, yet clear, correlation between the filamentary structures, detected with LOFAR, and the
magnetic field orientation, probed by the Planck satellite.
